Use the calculator provided to solve the following problems. Suppose that follows a chi-square distribution with degrees of freedom. Compute . Round your answer to at least three decimal places. Suppose again that follows a chi-square distribution with degrees of freedom. Find such that . Round your answer to at least two decimal places. Find the median of the chi-square distribution with degrees of freedom. Round your answer to at least two decimal places.

a) P(12≤χ²≤24)=0.690

b) k=35.85

c) Median=18.34

Step-by-step explanation:

The question is incomplete: "Use the calculator provided to solve the following problems. Suppose that χ² follows a chi-square distribution with 19 degrees of freedom. Compute P(12≤χ²≤24) . Round your answer to at least three decimal places.

Suppose again that χ² follows a chi-square distribution with 19 degrees of freedom. Find k such that P(χ²>k)=0.025. Round your answer to at least two decimal places.

Find the median of the chi-square distribution with 19 degrees of freedom. Round your answer to at least two decimal places."

Compute P(12≤χ²≤24)

Find k such that P(χ²>k)=0.025

The median of the chi-square is:

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230
